Abstract

La présente invention concerne une hotte de cuisinière comprenant une hotte dotée d'un passage d'écoulement d'air, un ventilateur de décharge d'air prévu dans le passage d'écoulement d'air, un filtre prévu dans le passage d'écoulement d'air, un boîtier de nettoyage pour entourer et recouvrir une extrémité périphérique extérieure du filtre, une tuyère dotée d'ouvertures d'éjection qui font face au filtre, une section d'alimentation en eau pour distribuer de l'eau à la tuyère, et une section de récupération pour récupérer l'eau éparpillée dans le boîtier de nettoyage. Le filtre tourne autour de son axe central et comprend l'extrémité périphérique extérieure. Le filtre comprend une surface utile pour permettre à l'air de passer à travers celui-ci afin de capturer des objets minuscules. La surface utile présente une extrémité périphérique intérieure qui entoure l'axe central. Les ouvertures d'éjection sont agencées sur une ligne prédéterminée, de l'extrémité périphérique intérieure à l'extrémité périphérique extérieure de la surface utile du filtre. Dans la hotte de cuisinière, une tache collée au filtre peut être éliminée sans détacher le filtre et la dégradation des performances de décharge d'air est empêchée.
